TURBINE-MOTOR.

SPECIFICATION forming part of Letters Patent No. 729,513, dated May 26, 19 03.

Application filed September 19, 1902. Serial No. 123,981. (No model.)

T 0 all whom it may concern:

Be it known that 1, JAMES E. SHERIFF, a citizen of the United States,and a resident of the borough of Manhattan, in the city and State of New York, have invented a new and useful Turbine-Motor, of which the following is a specification.

My invention relates to turbine-motors, with the object in view of providing a turbine-motor in which the efliciency of the motor shall be maintained under a given size and velocity of fluid jet while the speed of the motor is materially reduced.

A practical embodiment of my invention is represented in the accompanying drawings;

in which-- Figure 1 is a vertical longitudinal section in the plane of the line A A, Fig. 2. 2 is a transverse vertical section in the plane of the line B B, Fig. 1:. Fig. '3 is a horizontal section in the plane of the line C C, Fig. 1; I

and Figs. 4 and 5 represent, respectively, a horizontal section and partial vertical section of a modified form.

The wheel 1 is mounted between the two snail-shaped compartments or chambers 2 and 3 of the casing and permits the escape of the driving fluid from what I am pleased to call the impact-chamber 2 into the exhaustchamber 3, through the spaces between the blades 4 only, except such small amount-as may escapethrough narrow space required for clearance.

The primary nozzle for injecting the driving fluid, either-a gas, vapor, or liquid, into the impact-chamber 2 is denoted by 5. In-- termediate of the nozzle'5 and the wheel 1, along the neck of the chamber-2, I locate a series of nozzles, in the present instance four, (denoted by 6, 7, 8, and 9,) each succeeding nozzle from the injecting-nozzle inward being provided with an opening of greater diameter than the preceding one for the purpose of enlarging the jet by accretion. This series of nozzles above referred to will be called, for convenience, jet-enlarging nozzles.

In order that the enlarged jet may have a specific gravity equal-to or greater than the original jet, and so maintainits energy under a given velocity, I expose the inlet endsof the jet-enlarging nozzles to a-supply of fluid, in the present instance from the exhaust-chamber 3, through a large opening 10 between the necks of the chambers 2 and3. The exhaustopening 11 is located on the opposite side of the neck of the chamber 2 from the opening 10, so that the fluid passing from the exhaustchamber 3 is required to pass between the jet-enlarging nozzles around the original jet, where more or less of the fluid may be drawn in by the driving-jet and carried along with it asthe driving-jet is allowed to expand by the addition of the fluid from the exhaustchamber.

The. enlarging of the driving-jet will tend to materially reduce its velocity, and hence in order to maintain its driving energy at such reduced velocity the impact-surface on the wheel is proportionately increased. This may be done, by increasing the number of blades 4 or byincreasing the impact-surface on each blade by making it wider or longer, or both, so that, for instance, if the velocity of the enlarged jet be one-half the velocity of the original 'jet the impact-surface on the wheel for receiving the enlarged jet shall be twice the area of that required for the best results from the original jet. By this arrangement I secure a comparatively slow rotary movement of the wheel, a feature of the utmost importance, because of the saving in wear and tear, and at the same time the driving energy of the original jet is maintained or increased.

The form shown in Figs. & and 5 is applicable to turbine-motors in which jets are applied to the wheel at one or more places throughout its periphery. The jet-nozzle is denoted by 12. The series of jet-enlarging nozzles is denoted as a whole by 13, the wheel by 14:, its blades by 15, and the casing for housing the wheel by 16.

It is obvious that the number of jet-enlarging nozzles and their relative distances apart, as well as the shape of the wheel-casing and its blades, may be varied without departing from the spirit and scope of my invention.

Hence I do not wish to limlt myself strictly to the structure herein shown and described; but

\Vhat I claim is 1. In combination, a turbine-wheel, a plurality of jet-enlarging nozzles for directing the fluid to the Wheel and means for directing the exhaust fluid from the Wheel to an opening between two of the said nozzles.

2. In combination, a turbine-Wheel, a primary nozzle for directing a jet of fluid to the wheel, a series of jet-enlarging nozzles intermediate of the primary nozzle and the wheel and means for directing the exhaust fluid from the wheel to the series of enlargingnozzles.

In combination, a turbine-wheel, a primary nozzle for directing a jet of fluid to the Wheel, a series of jet-enlarging nozzles located intermediate of the primary nozzle and Wheel, an exhaust-chamber in communication with the Wheel and the series of jet-enlarging nozzles, at one side thereof and an exhaustoutlet at the opposite side of the said series of jet-enlarging nozzles.

4. In combination, an impact-chamber and an exhaust-chamber arranged side by side, a turbine-wheel intermediate of the two chambers, a primary nozzle for directing a jet of fluid into the neck of the impact-chamber, an opening from the neck of the exhaust-chamber into the neck of the impact-chamber and a series of j et-enlarging nozzles located in the neck of the impact-chamber opposite the said opening.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two Witnesses, this 13th day of Sep tember, 1902.

JAMES E. SHERIFF.
